To date, many different materials can be inserted to the patient artificial teeth. Cermet is the most popular of them. It is a modern prosthetic design in the form of crowns and bridges. It is a metallic base replicating the shape of the tooth is covered with a thin ceramic layer.
The use of sintered metal
In what case is the prosthesis made of this material? Often patients come to the dentist with the complaint that the carious process is partly or two thirds of the affected teeth. Metal in this case will be the material that the doctor will suggest to take for making the crown.
For reviews of orthopedics, bridges of this type will be a robust design in the absence of one or more teeth. His mount is on a support. The prosthesis is between them. As supports used healthy teeth, located on the border of the defect. On them and put metal-ceramic crowns. Between these legs is fixed the intermediate part, compensate for missing teeth.
The metal generally recommended, chewing on the jaw area. This confirms the reliability of the material used. Can be installed metal on the front teeth. However, in the opinion of patients, such a prosthesis is illuminated through the coating. It makes ugly front teeth. Metal in this case is used on a frame made of zirconium dioxide or oxide. Such dentures are more aesthetic.
Cermets are used in cases when use of the crown on the pins. This magnificent material for artificial teeth.
In dental practice there are cases when the doctor recommends conducting metal-ceramic prosthesis only. This happens:
– when you change the color or shape of natural teeth due to the presence of any pathology
– with increased abrasion of the enamel
– if there are congenital anomalies of the face in an unnatural location of the teeth and so on.
- when replacing existing non-removable metal prostheses;
– if the patient may be allergic to plastic design.
Warnings for prosthetics
Is it always dentists recommend to their patients the metal? The doctors say that you can't install this design in the following cases:
– thinning of the enamel on the abutment teeth if the crowns are flat and low
– in the absence of more than four teeth in a row
– when the bridge construction during the deformation will result in chipping in the deposition of ceramics.
Before to install the metal crown, the dentist needs to measure the wall thickness of the teeth. This is an important procedure, since the small amount of solid tissue there is a risk of opening the tooth cavity.
What is a metal-ceramic construction? These are artificial limbs, the skeleton of which is made of precious, semiprecious or non-precious metal.
On its surface poured or sprayed dental ceramics. In contrast to those composites that were used in the past, metal crowns perfectly reproduce the structure and color of natural tooth enamel. For reviews many patients, the aesthetic appearance of such structures does not change for a long time. They do not fade and do not absorb any colouring substances.
Positive and negative characteristics of the cermet
Before a prosthesis of the mouth, many patients are carefully studying the properties proposed by the orthopedic material. Often they wonder: "For those who decided to put teeth metal harmful or not?". According to specialists, negative effects on the body of this material is minimal, if meets all standards of manufacture and installation design. No harm to health will not bring these teeth. Metal is absolutely non-toxic. However, in the opinion of patients, structures made from chromium-Nickel alloys, are often threatened with Nickel allergies. Crowns made of base metals eventually oxidize under the influence of saliva.
Plus metal is enclosed in its high strength and long service life. The disadvantage of this material is the possibility of thinning of the enamel. While unsightly starting to look exposed silver frame. The negative side of such a prosthesis is that you need a fairly strong grinding teeth under cermets. Sometimes even resort to depulpatsii.
The service life of metal-ceramic prostheses
The design of this modern material are most often used on those teeth that carry the load of chewing. This is due to the high strength of the cermet. However, this characteristic, according to experts, causes premature wear, which is observed from the opposite teeth.
How long can you stand metal (teeth)? Many patients confirm that one should not hope to use such a prosthesis the rest of her life. Over time, it is the same as all the others, will require replacement. On average, the prosthesis made of this material with a basis of base alloy is from 10 to 12 years. Longer service life of structures made of gold-platinum alloy. It may exceed the threshold in 15 years. However, it should be remembered that the patient should follow all the rules of caring for ceramic prosthesis.
In this design there is no mandatory guarantee. Clinic give it in the range of one to three years. Specific dates depend on which alloy was used in the manufacture of the frame. The guarantee means that within the specified period, the crown will retain its original integrity and will not collapse from produced by mechanical impacts.
Often the design falls out from secondary caries, which develops under them in the teeth. To prolong the life of the structure and to avoid such a situation, experts recommend their patients undergo regular preventive inspections and timely replacement of old dentures with the new one.
Probability of allergic reactions
For reviews of patients, metal crowns are completely hypoallergenic. However, in rare cases, the negative reaction of the negative impact of the metal frame. Its symptoms are burning sensation in tongue and gums. Sometimes there are complaints of the patients the swelling of gums and swelling. In the mouth of such prostheses may receive a distinctive metallic taste. If you experience the above described symptoms, the patient should consult a doctor who will probably advise you to replace the metal on metal crown.
Ceramic coating used for durable and reliable constructions, easily mimics the structure and color of the natural enamel. While the prosthetic tooth is most similar to the nearby "native". Such a gorgeous aesthetic properties noted by the majority of patients, setting a metal-ceramic design.
Gone are the days when fashion was considered unnatural Hollywood smile. With rare exceptions it is not combined with well-preserved dentition. Today, there are appliances interior painting ceramics. Its basic principle is concluded that the characteristic features of the natural teeth of a patient are modeled inside of the structure, not affixed to its surface. During the development of this equipment was taken into account and that the natural enamel has a certain Shine.
For reviews of some patients, cermet, mounted in their oral cavity, over time began to blacken. The reason is very simple – people just forgetting to brush your teeth. Therefore, it is worth to remember about individual hygiene of the oral cavity. It is important for everyone, but especially it needs to respect people, embedded metal-ceramic prostheses.
Precious Metal Frame
The base metal structures may be made of various metals. However, the most popular, reviews of patients, uses the prosthesis on a gold alloy, which can contain palladium and platinum. This cermet is the most preferred. The fact that gold is not affected by oxidative reactions in the interaction with saliva and, as a biocompatible material that is not rejected by the body.
The installation of the cermet
For those patients who have decided to replenish your teeth with dentures made of this material, you will need to pass a preliminary diagnosis. You will need to produce and the preparation of the abutment teeth. Only after that the orthopedic surgeon will do all the necessary casts, to make an individual design.
It is worth remembering that the teeth under cermets needs to be honed thoroughly. This is due to the width of the walls of the crowns, which is greater than that of other types of prostheses.
Metal, usually installed on the teeth with the shoulder. To create a podiatrist and grinds the natural enamel. Such actions in the future to avoid touching the metal frame with the gum, which will significantly reduce the risk of irritation, swelling, allergies and bleeding in the oral cavity.
Caring for metal-ceramic prostheses is very simple. It is completely different from the usual hygienic procedures of the oral cavity. Patient with metal-ceramic prostheses must brush your teeth in the morning and evenings as well if possible, and every time after a meal. It is worth remembering that the hygiene procedure should be carried out according to the usual rules.
Dentists warn that if in the process of cleaning the metal will appear painful sensations in the teeth, under dentures, you should immediately consult a specialist. This symptom may indicate the development of secondary caries.
The need for restoration
Situations in life happen different, and sometimes metal is damaged as a result of mechanical stress. So, maybe to break away the upper layer of the structure. For its restoration specialist, primarily, evaluates the scope of the problem. First, it checks whether the exposed metal frame. If this happens, then most likely, the orthopedist will offer to remove existing structure and install the new one. The restoration of ceramics with a slight chip maybe directly in the oral cavity. That won't hurt teeth. Cermets before and after such procedures have been and will remain a reliable design for his master.
What is the cost of metal-ceramic teeth? It consists of the price of:
- production of orthopedic structures in a dental laboratory;
- turning teeth;
- installation of a prosthesis with an orthopedist.
In addition, the cost of porcelain fused to metal teeth depends on the price category of the clinic. Affects the quality of the material used in the manufacture of the frame. What is the payment will have to make those in the capital have decided that it is suitable in order to put teeth metal? Moscow offers next the cost of these implants:
- in economical dentistry - within 7,000 rubles;
- in premium class clinics - up to 40,000 rubles.
Metal (teeth), the price is for one crown is in the range of 3000 RUB is likely stamped design. With a lack of available funds, the cost of prosthetics can be somewhat reduced. On lateral teeth and wisdom teeth it is necessary to put crowns made of plastic.
